Car enthusiasts and mechanics, listen up! If you're working on older Chevrolet or GMC trucks from the late 80s to early 90s, these TBI fuel injector connectors are exactly what you need for repairs and replacements. These are 2-pin connectors with 7.48-inch long wires (that's 19cm) made from 18AWG PTFE wire with nylon plastic housing and high-quality copper wire inside. The construction is seriously durable - they're resistant to moisture, heat, and shrinkage, which prevents joint corrosion and lets them handle extreme temperatures without issues. What's great about the tinned copper stranded wire is that it provides better conductivity and corrosion resistance compared to bare copper, extending the harness life by like 30% or more. The compatibility list is pretty extensive - we're talking Chevy C/K series trucks from 1988-1991, Caprice, Lumina APV, S10, Blazer, and similar models from GMC, Oldsmobile, and Pontiac from around the same era. The OE numbers match 12102568 and 85139, so you know you're getting the right fit. These connectors are all about reliable performance - low-loss transmission means minimal signal attenuation and distortion, keeping everything running smoothly. Just make sure to double-check the shape, terminals, contacts, and pin quantity before ordering to ensure compatibility with your specific vehicle. If you're unsure, the seller can provide more details. For anyone maintaining or restoring these classic trucks, having these quality connectors on hand is just smart maintenance.
